Hello,
Your system does not recognize my business tax number as valid. In Settings > Billing > Payment Information, bottom of the page, I entered my business name and GST number (for Canada); it has 15 digits (alpha and numerical) but I get an error message: ''GST/HST registration number provided is invalid''.
I can assure you that I entered the correct information. Please fix this issue asap as you are about to charge me for my annual renewal.
Thanks.
